Jared Becksfort commented on MATH-815:
--------------------------------------
That is OK with me, but the getKernel function has a bug. If you are OK having it in the
repository for a day or so, then we can do that. If you would rather not have a bug there,
you can attach your version of MultivariateNormalDistribution.java and I can modify it and
resubmit.

I would like to submit it to Apache Commons Math. I still have some touching up to do so
that they fit the style guidelines and implement the correct interfaces. Before I do so,
I thought I would at least ask if the developers of the project are interested in me submitting
them.

> Dear Jared,
> Yes, that would be very nice to have such an addition! Remember to also include unit
tests (refer to the current ones for examples). The best would be to split a submission up
into multiple minor ones, each covering a natural submission (e.g. multivariate Normal distribution
in one submission), and create an issue as described at http://commons.apache.org/math/issue-tracking.html
.
